T0 aZZ whom it may concern.-

Be it known that I, PAUL MAUSER, a subject of the Emperor of Germany,residing in Oberndorf-on-the-Neckar, in the Kingdom of IViirtemberg,Germany, have invented certain new and useful Improvements in Bolt-Stopswith Cartridge-Shell Ejectors for Breech-Loading Bolt-Guns, of which thefollowing is a specification.

This invention is the subject-matter of Letters Patent in Belgium, No.86,375, dated May 25, 1889; in Germany, No. 50,306, dated June 30, 1889in England, No.18,014, dated N ovember 12, 1889; in Italy, No. 26,450/137, dated December 31, 1889, and in Spain, No. 10,226, dated February1, 1890.

This invention provides an improved boltstopping device forbreech-loading fire-arms of the class known as bolt-guns. XVith theboltstop is combined a shell-ejector, and in case the gun is providedwith cartridges by means of my improved cartridge-frame patented to meby United States Patent No. 402,t 305, dated May 7, 1889, thebolt-stopping device is provided also with a spring-catch for holdingthis frame during the insertion of the cartridges.

The main parts of the invention-namely, the bolt-stop and theejector-can be applied to existing breech-loading bolt-guns of theMauser system, and they are also applicable to other systems ofbreech-loading bolt-guns and to single-loaders and repeaters.

In the accompanying drawings the invention is shown as applied to a gun,the bolt of which is formed on its front end with two recoilprojections, which, When the bolt is in place for firing, enter intorecesses formed in the breech-case, and to the breech-case of which isapplied at the under side a small cartridge-magazine, from which thecartridges rise into the breech-case through an opening in its bottom.

Figure 1 is a side view of the breech portion of the gun, partlybroken-away and in vertical mid-section. Fig. 2 is a verticalcross-section on the line 2 2 in Fig. 1. Fig. 3 is a plan or top view,partly in horizontal section, in the plane of the axis of the bolt. Fig.4 is a vertical cross-section on the line 4 4 in Fig. 3.

The breech-case is designated by hand the bolt by (t. In Fig. 1 the boltis shown pressed forward in position for firing, while in Fig. 3 it isshown drawn fully back. The bolt is formed at its front portion withrecoil projections a a on its opposite sides, which, when the bolt is inthe firing position, are turned so that they enter recesses 77/ h, asshown in Fig. 1, and as indicated by the dotted lines in Fig. '2. henthe bolt is oscillated and drawn back, these recoil projections movethrough grooves Win the breech-case. The bolt is also provided with theusual ejector-claw I), having a hooked end for engaging the base of thecartridge-shell.

On the left side of the breech-case h is formed a lug 71 to which ispivoted the boltstop j, which consists of an arm having a tooth ornosej, which projects through a slot or opening in the side of thebreech-case, and stands in the path of one of the recoil projections aof the bolt, so that as the latter is drawn back and this projectionstrikes the tooth j the bolt is stopped. The bolt-stop 7' is constructedin the form of a frame, which fits over andincloses thelug 72?, beingpivoted thereto by a vertical pin passed down through the frame and lug.The outerside of the frame is closed by a springj in the form of a flatplate fastened to the outer end of the arm j, and pressing at its freeend against the lug 72 so that it acts to press the arm j normally closeagainst the breech-case, and with its stop-tooth j in position toprevent the withdrawal of the bolt. By rocking the arm 7' outwardly,however, against the tension of this spring the tooth j may be carriedout of the way of the recoil projection to to permit the bolt to bedrawn out of the gun. By constructing the stop-arm j as a frame with itsplate-springj it is constituted a box closed on the outer side andhousing the lug 7L3 and the ejector and its spring and concealing theslot or opening inside of the breech-case.

lhe ejector consists of a flat plate g, preferably of steel, the pivotalend of which is mounted in a slot in the lug h where it turns on thesame pivot-pin as the bolt-stop j. The front portion or beak g of thisplate enters through a slot or opening in the breech-case andprojectsinto the latter, bearing against the side of the bolt to when it ismoved forward, being lightly pressed against the bolt by a spring 9arranged inside the boxshaped arm of the bolt-stop j. hen the bolt isdrawn back, the beak g of the ejector enters a slot or deep groove g,formed in its side at its front end, so that just before the boltreaches the end of its backward movement the beak, by entering thisslot, comes behind the base of the cartridge-shell, stopping at once itsfarther back motion, while the coil of the extract-or 1) draws the shellback a little farther until the bolt a is stopped by the bolt-stop j.The effect of these movements is to eject the shell by throwing ittoward the right, as shown by dotted lines in Fig. 3.

The front portion of the bolt-stop extends upward as a verticalprojection or arm 7' which is curved inwardly concentrically with therounded back portion of the breech-case 71. The upper end of this armprojects slightly into the vertical plane of the opening in the top ofthe breech-case for the insertion of the cartridges when filling thecartridge-maga zine, as is clearly shown in Fig. 4. By reason of thisprojection this end bears against the cartridge-frame q, which is shownin dotted lines in Figs. 1 and 4, when the latter is inserted into theloading-space of the breechcase, so that the arm 7' directs the frameinto its proper place and holds it there until the cartridges have beenpressed down into the magazine 1'), after which the frame q is easilyremoved. This frame q is the same as that shown in my patent, No.402,605, hcreinbefore referred to.

By swinging out the bolt-stopj toward the left not only is thestop-tooth j carried out of the way of the recoil-shoulder a but theejector g is also held out of reach of the bolt, and the bolt can thenbe removed entirely from the breech-case. In replacing the bolt it canbe pushed back to place without manipulating the bolt-stop, since theparts pass easily over the yielding oblique faces of the triggernose,the st'op-toothj, and the ej ector-beak g.

The bolt-stop provided by my present invention differs from that shownin my United States Patent, No. 406,024,, dated July 16, 1889, in thatthe recoil projections to a are formed at the front part of the bolt,and one of them constitutes the shoulder which encounters and isarrested by the stop-tooth, whereas in that patent the recoilprojections are formed at the rear part of the bolt and have noconnection with the bolt-stop, the shoulder which encounters thestop-tooth being formed on a non-oscillatin g slide which covers overthe top of the bolt and moves with it, being fastened to the bolt-head.By my present construction this slide is omitted, the bolt-head isformed integrally with or fast to the bolt, so as to oscillate with it,and the recoil projections by this new arrangement are made to perform adouble function. My present invention also introduces an improvedconstruction of the bolt-stop.

I claim as my invention the following defined novel features orimprovements, substantially as hereinbefore specified, namely 1. In abreech-loading bolt-gun, the combination, with the breech-case and bolt,the latter constructed with a recoil projection at its front partentering a socket in the front part of the breech-case when the bolt islocked, of a bolt-stop consisting of an arm pivoted to the exterior ofthe breech-case, having a stoptooth entering the latter and standing inthe path of said recoil projection, and a spring for holding said armagainst the breech-case.

2. In a breech-loading bolt-gun, the combination, with the breech-caseand belt, of a bolt-stop consisting of an arm pivoted to the exterior ofthe breech-case, having a stoptooth entering the latter, and said armformed as an open frame with a plate-spring for pressing the arm againstthe breech-case, arranged to close the outer side of said frame.

3. In a breech-loading bolt-gun,the combination, with the breech caseand bolt, the breech-case constructed with a pivot-lug on its side, of abolt-stop consisting of an arm on the side of the breech-case pivoted tosaid lug, having a stop-tooth entering a slot in the breech-case, andsaid arm formed as an open frame inclosing said lug, and a plate-springclosing the outer side of said frame, fastened to the free end thereofand pressing against said lug to hold the arm pressed against the sideof the breech-case.

4. In a breech-loading bolt-gun, the combination, with the breech-caseand bolt, the latter formed with a groove in its side at its front end,of a bolt-stop consisting of an arm pivoted to the exterior of thebreech-case and having a stop-tooth entering the latter, an ejectorconsisting of an arm pivoted to the side of the breech-case and havingits beak entering the latter in line with the groove in the bolt, andadapted to enter it when the bolt is drawn back, and a spring reactingagainst the bolt-stop and bearing against the ejector to press its beakinward.

5. In a breech-loading bolt-gun, the combination, with the breech-caseand bolt, the latter formed with a groove in its side at its front end,of a bolt-stop consisting of an arm pivot-ed to the exterior of thebreech-case and having a stop-tooth entering the latter, and formed as ahollow frame or box, an ejector consisting of a pivoted arm workingwithin the hollow of said frame with its beak projecting into thebreech-case in line with and adapted to enter the groove in the bolt,and a spring for pressing said ejectorarm inwardly.

6.

7. In a breech-loading bolt-gun, the combination, with the breech -caseand bolt, the former having a pivotal lug on its side, of a bolt-stopconsisting of an arm constructed as an open frame, inclosing said lugand having a stop -tooth entering the breech case, an ejector consistingof an arm pivoted to said lugby the same pivot-pin as the stop arm andhoused within the latter, and springs for pressing said stop-arm andejector inwardly.

8. In a breech-loading bolt-gun, the combination, with the breech-caseadapted for the attachment of a magazine beneath and having acorresponding loading-opening in its top, of an armj, pivoted to thebreech-case and having a projectionj terminating at the top of thebreech-case at said loading-opening, and a spring acting against saidarm and I tending to press said projection into the opening, whereby theoperation of loading the magazine with cartridges held in a holderengaging their bases is facilitated.

9. In a breech-loading bolt-gun, the combination, with the breech-caseadapted for the attachment of a magazine beneath and having acorresponding loadingopening in its top, and the bolt having astop-shoulder, of the bolt-stop j, consisting of a spring-pressed armpivoted to the exteriorof the breech-case and having a stop-nosey"projecting into the breech-case in the path of said shoulder, and anextension j projecting over the top of the breech-case and terminatingat said loadingopening.

10. In a breech-loading bolt-gun, the combination, with the breech-caseand bolt, the latter formed with recoil projections on its front end anda groove in one of them extending into the front end of the bolt, of thebolt-stop j, with its stop-nose j entering the breech-case in the pathof said grooved recoil projection, pivoted to a lug h on thebreech-case, the ejector g, also pivoted to said lug and having abeak gentering the breechcase in position to enter said groove when the boltis drawn back, and a spring 9 for pressing said ejector inwardly.
